Dr. Martha Reyes


I grew up in Laredo, Texas, on the border to Mexico, and always knew I wanted to combine my love for animals with my community’s need for veterinary care. Now as a veterinarian, I have the opportunity to teach pet parents preventive and quality medicine that will provide them a meaningful relationship with their family pets.

I attended Texas A&M International University in Laredo and earned a Bachelor’s degree in biology with a minor in music in 2013. I attended North Carolina State University College of Veterinary Medicine in Raleigh, NC, and was awarded my Doctor of Veterinary Medicine degree in 2018. For the last 6 years since graduation, I have worked at corporations like Banfield Pet Hospital and Petco’s Vetco Total Care in Cary, NC, before I moved back home to Laredo. I have developed personal interests in preventive care, dentistry and oral surgery, internal medicine, soft tissue surgery, and urgent care/emergency services.

In my free time, I enjoy traveling and vacationing, being crafty, and spending time with my precious kids Antonio and Violeta!

I look forward to getting to know you and your fur-babies!
